Having won the league title in each of his last seven seasons - four with Juventus, three with Bayern - Vidal has become accustomed to a certain level of success, and he wants to continue that in Spain.

"To be honest I am very happy," he told Barcelona's official website. "I am looking forward to starting training with my teammates, to wearing such a famous shirt, and to doing important things here.

"It is a dream. I hope to achieve my objectives. I am here to win all the trophies available and I will give everything on the pitch to achieve this."

"[I will bring] a lot of fight, lots of passion, helping the team at all times, and making sure the team always wins."

Vidal and Barcelona share a common goal: to win the Champions League. Vidal was a runner-up with Juventus in 2015 and Barcelona have witnessed their rivals Real Madrid win the trophy in each of the last three seasons.
